Free summons get a Mystic buff! 
The free ad summon in the Daily Summon Gate has received an upgrade. The new Daily Mystic Summon can be drawn once a day in exchange for watching a Mystic Vision ad. Rewards can include more than one Hero AND there’s a chance of a bonus draw of a Trainer Hero, giving up to 20x the total XP of the old ad summon!
Thank you for your continued interest and support. Best of luck in the battles!
